overclocking better, resulting in more overclocking headroom. GPUs are the most popular component to overclock despite downsides. In terms of complexity, RAM (Random-access memory) is closely tied with CPUs, but performance gains are not as significant. In particular, DDR4 SDRAM is more prominent compared to its predecessors DDR3 and DDR2. However, even though higher speeds aren't usually very noticeable in most applications there are a few scenarios where overclocking RAM is legitimately important. One such scenario is with AMD Accelerated Processing Units where the CPU and GPU are combined in one chip, meaning they have to share memory resources. Typically, a GPU has its own RAM that is much faster than desktop DDR3 or DDR4 SDRAM, but with an APU it has to work with slower desktop RAM. In this particular scenario, overclocking RAM is highly recommended, giving meaningful performance increases.
